Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Stewed French Beans
Ingredients
Directions
Prepare
Bring water with salt to a boil and cook the beans until just tender.
Drain the beans in a colander.
Make the sauce
In a saucepan, whisk the egg yolks and cream together.
Add butter to the saucepan and heat over low flame.
Once hot, add the beans and vinegar, and simmer until tender, stirring to prevent curdling.
Replace egg and cream with gravy.
Use half the butter.
Add flour to thicken after adding the beans.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce and add richness as they set with gentle heat.
- Cream
- Adds richness and a smooth, velvety texture to the sauce.
- Butter
- Adds fat for richness and a silky mouthfeel.
- Flour
- Thickens the sauce so it clings to the beans.
- Vinegar
- Adds acidity that brightens the rich sauce.
The step that matters
Stirring while the beans and vinegar simmer in the egg mixture. Egg yolks curdle when they get too hot or heat unevenly. Keeping the heat low and stirring constantly lets the yolks thicken the sauce smoothly instead of scrambling it.
